The Metropolitan Crime Commission has asked the New Orleans District Attorney's office to investigate the death of a K-9 unit dog, who apparently died of a heat stroke after being left unattended inside a NOPD vehicle in late May.

A WWL-TV report cites a letter from MCC President Rafael Goyenche to Orleans Parish District Attorney Leon Cannizzaro.

A necropsy report by the Louisiana Animal Disease Diagnostic Laboratory showed that the dog, Primo had a temperature of 109.8 degrees when he collapsed at a veterinarians' clinic.

The dog died after he was transferred to the Southeast Veterinary Emergency and Critical Care Clinic in Metairie where he received emergency treatment, the report said.

According to WWL-TV, Goyenche's letter to Cannizzaro also asks that the office investigate the deaths of K-9 Phantom, who died after falling 18 floors down an elevator shaft in training exercise, and K-9 Carlos, who died from heart worms.

Cannizzaro told the Times-Picayune on Monday that his office is investigating incidents. He declined further comment.
